hi, is it possible to increase the available memory for a microblaze after it has been created ? .. i have created a microblaze with 16kb blockram using the base system builder, but now i want to use 32kb .. can this be changed?
Yes, you can either edit the MHS file and change the HIGHADDR of the memory controller, or you can edit it from the Address view in XPS.
will this also make xps initialize more bram? if i for instance build a system with 16kb block ram it automaticaly assigns 32K for dlmb_cntlr, but that dosent mean it has 32K of blockram .. if i use more that 16K for application code the compiler complains..
That is exactly what it will do. When you change the HIGHADDR (or memory size in XPS address view) you will get 32K of BRAM for program storage. Of course this needs additional 8 BRAMs.
